Given comments in your last post I'd go with:

40mm Paragon for widest apparent field of view (AFOV) - based on reports mainly on cloudynights.com

20mm Pentax XW for general purpose "workhorse" - based on my exp with 7,10,14mm XWs; amazing EPs - do some things better than Naglers. Amazing optical performance and the best made EPs I've ever seen ito fit, finish & build quality.

... And if it's got to be a barlow, I'd go for a low power one to get more use out of it: Antares 1.6x 2" barlow. On it's own it magnifies 1.5-1.7x. Add a 2" barrel extension you get about 2.0-2.2x depending on the EP. And it is a very good quality Japanese made barlow. You have to order this from o/s I think. I got mine from Scopestuff. Or for not much more money you could skip the barlow and get 1 or 2 more excellent bang-for-buck EPs, eg Pentax XFs, TMB Planetaries, UO HD orthos in the 8-12mm range.

This selection is within your budget and a comprehensive set that covers pretty much everything from low to high powers.
